onsemi · ESD And Surge Protection (TVS/ESD) · SOT-723
ESD7C3.3DT5G from onsemi, in a SOT-723. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CATHODE | passive | Cathode terminal of the ESD protection diode; pins 1 and 2 are both cathode leads. Device rated ±8.0 kV contact and ±15 kV air per IEC 61000-4-2 with a 3.3 V working peak reverse voltage (VRWM max). |
| 2 | CATHODE | passive | Cathode terminal of the ESD protection diode; pin 2 is the second cathode lead, same as pin 1. Device rated ±8.0 kV contact and ±15 kV air per IEC 61000-4-2 with a 3.3 V working peak reverse voltage (VRWM max). |
| 3 | ANODE | passive | Anode terminal of the ESD protection diode. Device rated ±8.0 kV contact and ±15 kV air per IEC 61000-4-2 with a 3.3 V working peak reverse voltage (VRWM max). |

- Symbol: `ESD7C3.3DT5G`
- Footprint: `Package_TO_SOT_SMD:SOT-723`
- 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `esd7c3-3dt5g-etched.step` / `esd7c3-3dt5g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `esd7c3-3dt5g.step` / `esd7c3-3dt5g.glb` are the bare package body.
